ABOUT THIS IMAGE:

This color composite focuses on the 26-mile-diameter
(42-kilometer-diameter) Aristarchus impact crater, and employs
ultraviolet- to visible-color-ratio information to accentuate
differences that are potentially diagnostic of ilmenite- (i.e, titanium
oxide) bearing materials as well as pyroclastic glasses. The symphony of
color within the Aristarchus crater clearly shows a diversity of
materials — anorthosite, basalt, and olivine. The images were acquired
Aug. 21, 2005. The processing was accomplished by the Hubble Space
Telescope Lunar Exploration Team at NASA's Goddard Space Flight Center,
Northwestern University, and the Space Telescope Science Institute.
False-color images were constructed using the red channel as 502/250
nanometers; the green as 502 nanometers; and the blue as 250/658
nanometers. North is at the top in the image.
